covtool
a multitool for manipulating coverage traces for dynamic analysis
primarily built around the standard-ish DrCov coverage trace format; but supports converting other, simpler trace formats. also supports a custom backwards-compatible extension to the DrCov format to track block hitcounts.
features
- a flagship tui for inspecting traces
- view stats about coverage traces
- perform queries (intersection, difference, etc.) on multiple traces
- edit traces (rebase modules, adjust offsets)
- lift simple formats to drcov (write your own coverage tools)
install
uv tool install covtool
coverage formats
flagship: drcov (+hits)
this is either the standard DrCov format (any version), or the custom extension to support hitcounts.
simple formats (lifted to drcov)
you can make a file that just outputs block traces in very simple formats (one entry per line).
these get auto-detected and can be converted to drcov using the lift tool:
- module+offset:
boombox+3a06 - address:
14000419cor0x14000419c - address+hits:
14000419c 24
you can lift to the standard format by specifying module names and optionally base addresses:
covtool lift input.txt -o output.drcov -M module@base_addr
